Displaying Page information (4 posts)

so im new so using wordpress and php so im learning as i go. what im trying to do is, for posts show the date that they were posted and i got that to work, but what that also did is when i click on a page link it also shows the date for that as well and i dont want that i just want posts to show the date and not pages to do that. does that make sense?, and is that possible?

oh i forgot to mention i am writing my own theme.. so how do i define the difference between posts, and pages for a page.php... ive been looking over different themes and im not quite sure on how to do it.. sorry if these questions are dumb
